Weighted spectral distribution

Spectral triples of weighted groups

We study spectral triples on (weighted) groups and consider functors between the categories of weighted groups and spectral triples. We study the properties of weights and the corresponding functor for spectral triples coming from discrete weighted groups.

Discrimination of Quaternary iron placer deposits by integrating remote sensing band ratio, magnetometry and geology data by weighted overlay index method compared to SAM and FCC methods in 1:100000 sheet of Hamedan

Abstract Quaternary placer deposits are becoming increasingly important. Remote sensing is a very powerful tool in discriminating altered areas related to intrusion deposits, which has significantly reduced the cost and time of exploration. In this study, to identify iron-bearing alluvial zones within the 1:100000 sheet of Hamedan, satellite image processing techniques such as band ratio (BR),...

Spectral Learning of General Weighted Automata via Constrained Matrix Completion

Many tasks in text and speech processing and computational biology require estimating functions mapping strings to real numbers. A broad class of such functions can be defined by weighted automata. Spectral methods based on the singular value decomposition of a Hankel matrix have been recently proposed for learning a probability distribution represented by a weighted automaton from a training s...

Weighted Log-spectral Amplitude Estimation with Generalized Gamma Distribution under Speech Presence Probability

In this paper, we propose a speech enhancement approach. The approach is based on deriving weighted log-spectral amplitude estimator that exploits the generalized Gamma distributed speech priors under speech presence probability. The log-spectral amplitude estimator is weighted by psychoacoustically motivated speech distortion measure to take advantage of the perceptual interpretation. The expe...

Skew-t distribution is an appropriate alternative for the weighted exponential distribution

In this manuscript first a brief introduction to the Skew-t and Weighted exponential distributions is considered and some of their important properties will be studied. Then we will show that the Skew-t distribution is prefered to the Weighted exponential distribution in fitting by using the real data. Finally we will prove our claim by using the simulation method.
